I have, for the cost of shipping (I'm guessing $5), two books that may be of
interest to folks interested in old telephone switching:
A Survey of Telephone Transmission - Pacific Telephone - 1956
Switching Systems - AT&T - 1961
These are cool books for your inner phone phreak.
Both books are in excellent condition. The first is soft cover, plastic
bound. The second is hard cover.
First person to agree to send me $5 gets them.
